If they are indeed conspecific, then Lamarck's name stands as the older and
valid senior synonym, and this name should be used. Unless, of course, there
is a problem with homonymy or some other complication.

Abbott 1974 makes no mention of either specific name, but makes a real hash
of the genera within the family.
